摘要： A liquid crystal display apparatus which has: a liquid crystal display which has chiral nematic liquid crystal between a pair of substrates with electrodes thereon and which makes a display by use of selective reflection of the liquid crystal; and a driving circuit for driving the liquid crystal by applying voltages to the electrodes. When an electric field of a specified strength is applied to the chiral nematic liquid crystal, the liquid crystal changes the direction of the helical axis without untwisting. By using this characteristic, the direction of the helical axis of the liquid crystal is changed by changing the direction of the electric field applied thereto, and thereby, the liquid crystal is set to a planar state or a focal-conic state. In this way, writing on the liquid crystal is carried out.
